Launch Base Beta Test

[Marshall]

Version 0.99.120 [2008-07-05]
When automatically checking for updates by launching a mod or using the right-click menu, if a mod has not specified an update check URL then Launch Base will log a message advising this.
When automatically checking for updates by launching a mod, Launch Base will skip checks where the user is launching a legacy version of a mod. When checking for updates using the right-click menu, legacy versions will cause Launch Base to check for updates to the most up-to-date installed version of the mod.
When checking for updates via the right-click menu, a message box should always be displayed regardless of the result of the update check.
Right-clicking on a banner on the mod banners view will show the same menu as right-clicking on the mods list.
Command line argument change: specifying an IPB file no longer requires the -play switch (which is no longer recognised). As such, IPB files can be associated with Launch Base so you can double-click on them. See Help Topics for more information about this change.
Added 'Associate With IPB Videos" button to Options window.
Launch Base setup program will erase the downloaded mod catalogue, in case any changes introduced in the latest version require the data to be updated.
Updated help topics.

Would like opinions on the eva sounds - considering removing them to reduce DL size as I don't think many people will want these.
